摘　　要：研究了用于控制高层钢结构建筑风振反应的粘弹性阻尼器 (VED)设计方法 .通过计算整体结构的有效阻尼比 ,建立了设置VED结构抗风设计的风振系数和脉动增大系数的调整公式 ,得到了设置VED结构在顺风向和横风向的层加速度计算方法 .并以例子证明了VED是一种有效的耗能减振构件 。A design method for wind resistance of steel tall buildings with the installation of viscoelastic dampers (VED) is presented. With the effective damping ratio of steel tall building installed with VED obtained, the revised formulas of wind vibration coefficient and fluctuation increment coefficient are established. The calculation methods of storey acceleration responses of the structure suppressed by VED in alongwind and acrosswind directions are introduced. The example of a 50 storey building is given to illustrate that the design method described in the paper is very convenient and effective, and practical for structural engineers.
